My goal is to install centos 8 as a virtual machine on ubuntu 18.04 and be able to access the internet on the virtual machine and to access the host file system from the virtual machine. Ideally I would like to have 2 ip addresses, one for the virtual machine and one for the host. The host has wireless connection.
I have successfully installed centos 8 on ubuntu 18.04 as virtual machine with the following command:
sudo virt-install --name=chris_centos --ram=2048 --vcpus=2 --cdrom=/var/lib/libvirt/images/CentOS-8.1.1911-x86_64-dvd1.iso --os-type=linux --os-variant=rhel7 --network bridge=virbr0 --graphics=spice --disk path=/var/lib/libvirt/images/chris_centos.dsk,size=10
The problem however is that I cannot access the internet nor the host file system.
[chh3@localhost ~]$ ping www.google.com
ping: www.google.com: Name or service not known
[chh3@localhost ~]$ ping 8.8.8.8
connect: Network is unreachable
[chh3@localhost ~]$ ping 192.168.1.68
connect: Network is unreachable
I am not sure how get connectivity. Some advice I got on one of the forums is that I cannot use a bridge when it I have a host wireless connection, other said I could. So I am confused. My current net work configuration is:

Is there a way to configure this or would I need to reinstall in a different way. I am new to this so I appreciate any help I can get.
